CORE DEFINITION

Fixedness: seeing only the conventional uses of an object. Blind spot: failing to think of unconventional uses. Obstacle: hindering creative problem-solving.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Recognize and break through fixed perceptions of an object's uses. Being aware that functional fixedness is a major obstacle to creativity, one can deliberately practice breaking it—asking "What else can this be used for?" Related variants: functional fixedness decomposition, functional fixedness breakthrough, functional fixedness breakthrough method.

Anchor fast decisions

Functional fixedness is a cognitive bias: people tend to associate only the conventional uses with an object, thereby failing to see unconventional creative uses, hindering problem-solving. Duncker's 'candle problem' classically demonstrates this—people find it difficult to see a box of tacks as a candle holder until they break the fixed framing.

The Forgetting Curve

The Forgetting Curve is a curve used to describe the rate of forgetting in long-term memory. It was first proposed by psychologist Hermann Ebbinghaus based on his experiments conducted from 1880 to 1885. In these experiments, Ebbinghaus used meaningless letter combinations. By memorizing these combinations and checking the forgetting rate after a series of time intervals, he obtained this curve. Therefore, this curve is also called the Ebbinghaus Forgetting Curve.
